Application

Isodur RN is a highly effective hardener and crosslinker for adhesives that are based on polyurethane. It improves heat stability, hydrolysis resistance, and the resistance to greases, oils, and solvents. Isodur RN results in optimal final bond strength and peel resistance. Compound materials will have good heat resistance.

Usage Information

After adding Isodur RN to a polyurethane- or rubber-based adhesive, the mixture must be used within its pot life. The pot life depends on the polymer content as well as on other ingredients like antioxidants, resins, plasticizers, solvents, etc. This pot life can vary from several hours to one day.

Handling, Storage, and Packaging

The processing and use of Isodur RN requires adequate technical and professional knowledge. Please consult safety data sheet and observe local safety regulations. The legal requirements prevailing in your country, especially in the avoidance of accidents, working hygiene and patent rights must be observed.

Isodur RN has to be stored in its sealed original containers at temperatures from 10 to 25°C. Properly stored it is stable for a minimum of six months. If it is stored or transported at low temperatures, crystalline deposits may form but they will re-dissolve at room temperature.
